James Cummisky

I am trying to help a woman find information on her ancestor, James Cummisky, who was fishing in a small boat when it capsized and he drowned, along with a "Mr. Johnson". This happened near Seattle (possibly Coupeville, Island County)in the Spring of 1906. A notice of his death appeared in the "Livingston Republican" newspaper (Michigan)on May 27, 1908, as he was a former resident of Iosco, Livingston County, MI. Any help appreciated.
